ORNAMENTAL GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 302,747, dated July 29,1884:.

Application filed April 14, 1884.

(Model.)

To aZZ whom it may concern:

Be it known that I, EDWARD D. Lrnnnv, of Boston, county of Suffolk,State of Massachw setts, have invented an Improvementin OrnamentalGlassware, of which the following de scription, in connection with theaccompanying drawings, is a specification, like letters on the drawingsrepresentinglike parts.

This invention has forits object the production of novel articles in cutglass,whereby new and beautiful effects are obtained. United StatesPatent No. 282,002 describes glassware composed of homogeneous glasshaving different colors blended one into the other. In that class ofglassware the color developed by heat ing is alike at both sides of theglass. In this my invention I employ substantially the same amberglassmixture containing the metal gold as is described in the said patent,and I shape the same in a mold, as practiced when forming articles whichare to be cut for the production of cut glassware, and then, with thethick article attached to a red, I present its outer face or base tohigh heat at the gloryhole or pot-hole, and give to the said base orouter face a rather deep color, or a color deeper than the inner face ofthe article against which the flame does not come in contact, asheretofore. The article so formed having been cooled, its base, or itsbase and outer side, are cut to present the desired pattern, and bymeans commonly employed to cut glassware for table use-as, for instance,a grindstonethe latter cutting into and more or less through the darkeror outer face of the article and into its lighter-colored body, thusadding a great variety of shade and variation in color and appearancenot heretofore obtained in cut glass.

ably darker in color than its inner surface.

The dish is then handed to the glass-cutter, who cuts through the rubypart into the body of the glass of lighter color, as shown in Fig.

2, thus leaving an article of glass cut at one side in pattern, the cutpassing through glass homogeneous in stock, but differing in depth ofcolor or shade from face to inner side, thus leaving glass of the darkercolor surrounded by and forming parts of a regular design or pattern,the out parts of which are lighter in color than are the uncut parts.

Articles of glassware, such as herein described, dishes for variouspurposes and for table use may be cut by grindstones in any usualpattern employed in cut flint-glass.

I claim- As an improved article of manufacture, glassware composed of ahomogeneous stock of deeper color at one than at its other side, and cutin pattern, the cuttings extendin g into the body of the glass, thusleaving spots of deeper color, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

EDVV. D. LIBBEY.
